How to update firmware over USB C

[MF_GS]

Hi,

My board with a STM32F745VEH6 is working as a device, that need to be updated via USB C over time. How can I do that? Is there a way to update the firmware with command line?

I tried to connect the micro over USB C with STM32CubeProgrammer, and got this error:

Do I have to have a ST-LINK on the board? Or use FTDI cable?

Are you using the correct USB pins (PA11 and PA12)?

Have you  activated the bootloader (BOOT pin) ?

Good point! Activate the BOOT pin and reset the micro helps! Thanks!

Do you have the suggestion for how to update the firmware with command line?
